Creating Backups 

There’s a lovely Unraid application called “CA Backup / Restore Appdata” which will allow one to automate the backing up of:

I leverage this tool to setup weekly backups of the folders described above, but we’re not done yet, as this stores the backups on the Unraid array itself. Generally data is not considered “backed up” until one follows the 3-2-1 rule.

3-2-1 Rule 

This rule states that “data is not backed up until its stored in three places, two different physical locations, one of which is off site”. Our usage of “CA Backup / Restore Appdata” makes it easy to create out backups but now we have to store them in two additional places, one of which should be off site.

Copying Backups 

To satisfy the 3-2-1 rule, I have a small script that will copy the backups from our Array to Unassigned Drive I have attached to my Unraid machine as well as send the data remotely to an offsite Raspberry Pi I have.

For those interested in these small scripts:

Moving Forward 

One additional step I could take is store our backups on some service that provides cloud storage. Something like S3 would work fine, but I’m particularly interested in the company Backblaze. They specialize in data hosting and produce these wonderful blog posts on the stats of hard drives. So what I would do is write an additional python script and add it to the described above, which would copy our backup to Backblaze as well.


Backups are really important. Not described here is how we would perform a restore with a given backup.

If you are not performing backups, I highly recommend spending the time now to set it up. The hours you spend configuring your host OS, the numerous containers etc is not worth gambling with.
